3.  Epigenetics are changes in gene expression; a change in phenotype without a change in the genotype.  This would be a change in the eye color but not the genes responsible for eye color. http://examples.yourdictionary.com/exam ples-of-genotype-phenotype.html

4.  Genotypes  Genes responsible for: Eye color Hair color Height Skin Color  Phenotypes  Physical Traits: o Eye color o Hair Color o Height o Skin Color http://examples.yourdictionary.com/examples-of-genotype-phenotype.html

5.  C.H. Waddington came up with epigenetics in 1942.  The words epigenetics comes from the two words epigenesis and genetics. http://en.wikipedia.org/wiki/Epigenetics https://sketchyintellect.wordpress.com/2012/03/25/waddingtons- definition-and-process-of-science/

6.  Robin Holliday, a British molecular biologist, defined epigenetics by saying, “the study of mechanisms and temporal and spatial control of gene activity during the development of organisms.” http://en.wikipedia.org/wiki/Robin_Holliday

7.  The term has been used to describe processes that are not heritable, like histone modification. This means there are attempts to widen the definition. http://en.wikipedia.org/wiki/Epigenetics
